This is a website that contains calculators for darkroom and film photography purposes. Many of these these calculators are based on exisiting algorithms, but have been put into a graphical web interface to be more user-friendly and easier to use.
- Darkroom easel border calculator, which calculates the easel blade positions of the easel for a given film and paper sizes, and displays a preview of the print on the paper.
- Stop-based exposure calculator, for calculating the exposure time when adjusting one's exposure based on the number of stops.
- Print resize calculator, for calculating the change in stops/seconds of the print when resizing the projection of an image on an enlarger.
- Color scheme switcher, with colorways in light, darkroom (red/black), and high contrast color (black/white for e-ink displays).
- Film exposure conversion calculator, which helps user maintain or change their relative exposure based on ISO, aperture, and shutter speed.
- Dilution calculator, which helps user calculate the amount of water needed to dilute a given amount of developer, including presets for various developers and dilution ratios.
- Film push/pull calculator, which helps user calculate the amount of time to push or pull their film based on the number of stops pushed or pulled when shooting.
- Reciprocity calculator, which helps user calculate the amount of time to add to their exposure based on the number of stops of reciprocity failure.
- Add disclaimers, instructions, and any other information to each page about the limitations of the calculators.
- Add an about page.
- Add toggle for metric/imperial units site-wide.
Pure HTML, Javascript, and CSS! No frameworks or libraries were used.
Otherwise, Prettier is used for consistent formatting, and gulp for a makeshift solution for cache clearing for the user by appending a timestamp to CSS and JS files cited in the HTML.
As this is a series of static web pages with no server-side elements, you can simply clone the repository or download the files and run them on an apache or nginx server. An easy way to get started is to clone the repository and install the VS Code Live Server extension, and run the home page index.html file.
